Body Weight Penalties In The Physical Fitness Tests Of The Army, Air Force, And Navy, Paul M. Vanderburgh, Todd A. Crowder

Health and Sport Science Faculty Publications

Recent research has empirically documented a consistent penalty against heavier service members for events identical or similar to those in the physical fitness tests of the Army, Air Force, and Navy. These penalties, not related to body fatness, are based on biological scaling models and have a physiologic basis. Using hypothetical cases, we quantified the penalties for males, 60 vs. 90 kg body weight, and females, 45 vs. 75 kg, to be 15-20% for the fitness tests of these three services. Such penalties alone can adversely impact awards and promotions for heavier service members. To deal equitably with these penalties …

Can Professional Development Programs Help Close The Achievement Gap?, C. Jayne Brahler

Health and Sport Science Faculty Publications

This paper explores the question of whether it is possible to design professional development programs for teachers that can significantly improve student test results and reduce the achievement gap for students.

The Dayton (Ohio) Foundation and the Montgomery County (Ohio) Educational Service Center, sponsors of The Miami Valley Teacher/Leadership Academy, answer this question with a resounding yes. Recent results indicate that the academy's two-year program, designed to provide professional development to help improve student test scores, not only succeeded in significantly improving the student proficiency mean score, but also considerably reduced the achievement gap for participating students.

Qtc Is Associated With Obesity And Physical Activity Level For African American Females, C. Jayne Brahler

Health and Sport Science Faculty Publications

Long QT syndrome (LQTS) is an independent risk factor for cardiovascular or ischemic disease mortality. Obesity as a cause for acquired LQTS in otherwise healthy individuals is rapidly gaining the attention of the scientific community. African American people have a higher incidence of obesity compared to Caucasians, yet race-specific information is not available for their prevalence of LQTS. Chronic physical activity can help reduce the incidence of obesity, yet little is known about the effects of chronic physical activity on acquired LQTS. Subjects in this study were a volunteer sample of African American mothers (21-53 yr, n = 44) and …

Acute Cardiovascular Response And Perception Of Effort Between The Super Slow And Gold Standard Resistance Training Protocols, Phillip Wickwire

Masters Theses & Specialist Projects

Super Slow training was proposed by Ken Hutchins in a book entitled Super Slow: The Ultimate Exercise Protocol (1992). Since then Super Slow training has been proposed to improve strength more effectively than traditional resistance training and improve cardiovascular measures above aerobic exercise. However, whether this type of training is safe for the older, possibly hypertensive population to which it is being targeted is questionable. To help provide an answer to this question the purpose of this study was to measure blood pressure, heart rate (HR), and ratings of perceived exertion (RPE) while performing the Super Slow resistance training protocol …

Focal Temperature Change Facilitates The Peak-To-Peak Soleus Hoffmann Reflex And Muscle Response, Bentley Andrew Krause

All-Inclusive List of Electronic Theses and Dissertations

Objective: Cryotherapy is a widely used rehabilitative modality in sports medicine. Cooling joint tissues has been observed to facilitate active exercise following injury. Mechanisms effecting motoneuron recruitment during and following cryotherapy are presumed to be both local and central in nature. Focal cooling facilitates motoncuron pool recruitment and may alter the excitability of motoncurons. The purpose of this investigation was to determine if changes in focal temperature alter the characteristics of the maximum peak-to-peak Hoffmann reflex (Hmax) and muscle response (Mmax). Design and setting: A 4x5 factorial design with repeated measures on time was used in this study. Hmax and …

A Motor And A Brake: Two Leg Extensor Muscles Acting At The Same Joint Manage Energy Differently In A Running Insect, Anna N. Ahn, Robert J. Full

All HMC Faculty Publications and Research

The individual muscles of a multiple muscle group at a given joint are often assumed to function synergistically to share the load during locomotion. We examined two leg extensors of a running cockroach to test the hypothesis that leg muscles within an anatomical muscle group necessarily manage (i.e. produce, store, transmit or absorb) energy similarly during running. Using electromyographic and video motion-analysis techniques, we determined that muscles 177c and 179 are both active during the first half of the stance period during muscle shortening. Using the in vivo strain and stimulation patterns determined during running, we measured muscle power output. …

A New Submaximal Bicycle Protocol For The Estimation Of Vo₂Max, Anna R. Bennett

Human Movement Studies & Special Education Theses & Dissertations

Simple, valid, and accurate means for estimating aerobic capacity from submaximal cycle ergometry are needed for use with the general public. Current popular methods such as the ACSM cycle ergometer protocol have been shown to overestimate maximal oxygen uptake (VO₂max) by as much as 26%. In the current study, VO₂max was estimated using a new protocol based on a single 6-min stage designed to elicit 70% HRR. The data was also used to estimate VO₂max by the Astrand method for comparison. Forty-nine healthy males and females, aged 18-44 yr (X = 26 ± …

Patellofemoral Joint Compressive Forces During Backward And Forward Running At The Same Speed, Hesham N. Alrowayeh

Rehabilitation Sciences Theses & Dissertations

A previous study found that the patellofemoral joint compressive force (PFJRF) during backward running was less than during forward running at free speed. Therefore, the purpose of this study was to compare the patellofemoral joint compressive forces during backward and forward running at the same speed. Ten runners (4 females, 6 males) between the age of 20-25 (X=22, SD=2) ran in backward and forward directions at the slow speed of 2.3 mph (1.0 m.sec^-1). Using the inverse dynamic technique the knee extensor moment and PFJRF during the slow backward and forward running were calculated. Results showed that the …
